Keywords
Here are some of the words we will be using this
lesson 1) Create sentences which use the
keywords correctly. 2) Put your hand up if there
is any key word from the list that you dont know
the meaning of.

• tarnish

6
Learning Activities for Outcome 1
The corrosion of metals
CORROSION is the gradual destruction of metal by
the effect of water, chemicals etc.
7
Tarnish
Rust
Rusting is a form of corrosion that affects only
iron and steel.
Tarnishing is a form of corrosion.  The metal
becomes dull and loses its colour.
8
Demonstration Investigating the rusting of iron
Look at the information given. What causes the
iron nail to rust? Explain/justify your answer.
9
Rusting of iron
Both air and water are needed for iron to rust.
Rusting is an oxidation reaction. The iron
reacts with water and oxygen to form hydrated
iron(III) oxide, which we see as rust. iron
water oxygen    ?    hydrated
iron(III)
oxide
Note You dont need to know the symbol equation
its rather complicated!
10
Demonstrate your Learning for Outcome 1
To know the difference between rusting and
corrosion
Evaluate (A) I can Justify the causes of rusting
based on experimental results.
Analyse (B) I can Distinguish between rusting and
corrosion
Apply (C) I can Identify the causes of rusting.
Understand (D) I can Explain the difference
between rusting and corrosion

Learning Activities for Outcome 2

• Research Task 1 - Comparing the properties of
  aluminium and iron

• Aluminium and iron are typical metals with many
  uses.
• What properties do they have in common?
• Below are some of the properties by which they
  differ.
• For each property describe their differences and
  suggest whether these differences are an
  advantage or disadvantage. Give an example of a
  common use for each advantage.
• Corrosion resistance
• Density
• Magnetic
• Cost

Research Task 2a - The construction of cars
Car part Properties needed Material(s)
Body
Cable for electrics
Carpet
Dashboard
Engine
Seat covers
Windows Transparent Glass, plastic
List the major materials used in a car and
explain why they are used. Describe the
advantages and disadvantages of building cars
from steel or from aluminium.
18
Research Task 2b Recycling of metals and cars
Every year in Europe, end of life vehicles
generate between 8 and 9 million tonnes of
waste. A European Directive requires car
manufacturers to improve their designs to make
cars easier to recycle.

• Look at your list of materials from Task 2a.
• Find out how recyclable they are. You should
  include
• Ease of separation.
• Ease of purification.
• Cost in .
• Cost in energy.
• Environmental impact.

Review

• Swap books with the person next to you and look
  over their work. Write a WWW and EBI statement.
• Stand up if you have developed some skills this
  lesson? What are they?
• Tell the person next to you three things you have
  learnt this lesson.
• Did you successfully complete tasks at your
  target grade?
• If not, what do you need to do next in order to
  meet your target grade? Record this in your diary
  to be done as part of your extended learning at
  home.
• Is there any part of the lesson you think you
  need to go over again next lesson?
• How will you remember what you have learned today
  for your exam?
